The first chromatic most people actually fight.
Wilderness bones. Protect item.
Slayer · Old School RuneScape
Lore
The first chromatic most people actually fight. Forinthry after the ditch. Dragonkin stock, not a pet. Bones and hides pay the trip. Protect item. Antifire. The player who walks in with a bank tab is the loot, not the dragon.
Where
Wilderness
Assigned by Old School slayer masters (Chaeldar through Duradel, and Konar). The live page lists who.
Hunt
Wilderness trip. Protect item. Antifire. Bones and hides. The ditch is the grammar.
Watch
Task-only doors, face covers, and cannon-blocks are on the live page. Confirm on the wiki.
Kill
A kill ends when green dragon drops. Walk the room if you pulled extras. Reset at the door when the task is done. Wrong prayer or the wrong tile is the wipe. That is the whole file. Do not treat a slayer floor as a raid invocation. Counts, drops, and the living method: the Old School wiki for this hour.
